Hunting For WWII Duds: German Firm Uses Aerial Photos to Find Bombs
By Andrew Curry in Würzburg, Germany
04/09/2012
A small German firm offers a unique service to the country's construction industry: It uses historical British and American aerial photography from World War II air strikes to determine the location of unexploded bombs. Thousands of tons of bombs still lie in the soil and the duds are becoming more dangerous.
Luftbilddatenbank, ... , specializes in finding bombs using old aerial photos

They are not the only firm doing that, had the opportunity to read one of those reports on the possibility of duds from the bombardment on the city of Mechelen, they are doing an extensive research since they are planning on building a new trainstation, they do not only try to find out where and how much but also the type so that they know what to expect, fortunatly the American and British air force kept track of most bombardment so most of the time it is mostly just counting the hits to find out how many duds they can expect
I heard about this over 15 years ago.
Before the construction of huge buildings is permitted a check for old bombs is standard, especially in Areas that were heavily bombed. (that means almost everywhere in Germany)
I wonder what the news about this is.
They've been doing that since the end of the war.
about 3 million bombs were dropped, an estimated 15% were duds
There is even a term for that: "historisch-genetische Rekonstruktion der Kampfmittelbelastung"

OFD Niedersachsen? Looks like KMR is provided by all kinds of state agencies across the Republic...
I work in the civil EOD contractor branch for about 11 years now.
Analyzing such images is part of my daily job.
I am also familiar with the Luftbildatenbank (who are pretty expensive compared to other archives).
Beside some national archives in the Netherlands i also use http://aerial.rcahms.gov.uk/ .
Just wondering, how the civilian EOD is organized in other countries.
lot of laws in Germany and a bit complicated:
First it is the Federal Constitution in the sense of "Protection from Dangers", then it derives from here. EOD is the responsibility of the Länder. Then every "Land" has it own official EOD, except Barvaria and Thuringia. The there are civilian EODs, either working as contractors for the Länder, or in the private sector.
In the Netherlands the demolition of UXO's is prohibited to the EODD. But historical research, detection (mostly by magneto meters), clearing and storage until demolition is done by civil contractors.
Most of the firms are certified according to the Netherlands Directive Detection and Clearance of Conventional Explosives (BRL-OCE and the upcoming CS-OCE regulations).
The object of the historical research is to establish on the basis of factual material if there is an increased chance of discovering conventional explosives in the area of interest.
The complete historical research consists of two parts: the problem inventory and the problem analysis.
During the detection phase the location of ferro-containing objects in the area of interest is digitally recorded.
This can be done on land as well as under water. It is also possible to link DGPS to these measurements to get a positional information of any present explosives as accurately as possible.
After the detection phase, and the reports of the spatial distribution, the "suspected objects" are then investigated further individually .
The locations are plotted in the field by means of DGPS in their x, y and z co-ordinate.
Using a cat. II secured excavator the points are dug up layer by layer under supervision of a Senior OCE expert, who subsequently identifies the object, its type,
condition and status (armed or not armed). Then he decides how the explosive has to be temporarily secured, in consultation with the Explosives Ordnance Disposal Command, if required.
OXU72, thanx, interesting info. Do you know usual percent for transported or destroyed-on-place items?
Only if the EODD want the item for their collection (rare items) or of it's a small item they take it with them. But most of the UXO's are blasted on site or at least nearby.Originally Posted by Pitchup
Good for you, our pyrotechnic groups, usually moving all items less then 250kg bombs to closest military training site. Sometimes it's tens of km away from place by bad public roads.
Next week we are going to clear 3 1000 lbs and 1 500 lbs bombs (3 US and 1 UK) and after the detonators are removed they are transported +/- 40 km to the detonation site.
So in some cases they are moved on the road.
